China Petroleum & Chemical Corporation News Network News Faced with the complex and volatile international environment and the ever-increasing energy demand, it is the responsibility that petroleum and petrochemical companies must shoulder to ensure national energy security
.
With the continuous deepening of China's oil and gas exploration, while the proven oil and gas reserves continue to maintain a relatively high growth, the proportion of low-grade and difficult-to-produce reserves is increasing
This requires that on the basis of not decelerating the development of conventional oil and gas, increase the development of difficult-to-use reserves, so that "low permeability, low pressure coefficient, low abundance, and deep-ultra-deep oil and gas reservoirs" have high production costs and low productivity.
Reservoirs have been effectively developed through innovative means to form adaptive development technologies to improve resource utilization and deal with unpredictable energy security issues in the future
.
Plan ahead to get the organization "moved"
How to make difficult-to-use reserves have industrial mining value? As early as 2019, Southwest Petroleum Engineering Company put this work on its agenda
.
A leading group and working group for reservoir integration were established
And organized a research team to the Difficult to Use Project Management Department of Shengli Petroleum Engineering Company to conduct research and study
.
Five scientific research projects have been set up around the development of difficult-to-use reserves, and special research projects on key technologies have been carried out
Fully guarantee, let the vanguard team "rush up"
The platform is completed, and the specific development work needs to be promoted quickly
.
The first step-drilling engineering design and preparation, the lead task falls to the Technology Research Institute of Drilling Engineering Research Institute of Southwest Petroleum Engineering Company
In order to eliminate the "psychological barriers for young people", the Party Committee of the Drilling Engineering Research Institute puts ideological work in the forefront, encourages young people to build confidence, encourages party members and leading cadres to take the lead and carry the red flag
.
The leadership team took the lead to provide strong support and provided "high-quality supply" in logistical support.
On the other hand, writers are encouraged to "practice" with the old wells of the past, from easy to difficult, to be proficient
.
At the same time, due to the different professional fields involved, the drilling fluid, gas drilling, cementing and other parts of the content were jointly compiled with relevant departments
Work together to make work more efficient
With the early "fully equipped", the writers enthusiastically launched the "real gun and live ammunition" attack, and soon they took out the first batch of wells in the 2 pilot test areas in the difficult-to-use reserve block.
-3 Well and Xinsheng 101-1 Well, the first draft of the design
.
On April 20, Southwest Engineering Company reviewed the design of two wells and put forward a large number of amendments
A series of actions of "gathering expert opinions, summarizing the previous issues, in-depth analysis and discussion, formulating rectification measures, item-by-item modification, optimization and re-optimization" was quickly set off.
After the modification, the institute was first reviewed, the courtyard was reviewed, and then submitted to the Southwest Project for re-review
.
"The geological basis is sufficient, the contents of drilling, logging, mud logging, cementing, and well completion are complete, the well depth structure is reasonable, and the corresponding drilling tool assembly meets the construction requirements
.
" On April 28, Southwest Engineering Company issued review opinions and passed the review unanimously.
As of June 16, the Technical Research Institute of the Drilling Engineering Research Institute has all completed the eight well drilling engineering design and writing tasks in the first phase of the difficult-to-use reserve cooperative development project
.
From receiving the task in early March to completing the first batch of 8 well design tasks at the end of June, from zero foundation and zero experience to confidence and ability, the Institute of Drilling Engineering Research Institute, with the strong support of the company, worked with brothers With the active help and the joint efforts of the whole institute, the company helped the company fire the first shot of the difficult-to-use reserves in the Southwest Industrial Area
.
It is believed that the difficult-to-use reserves will become an important battlefield for the high-speed and high-efficiency "increasing reserves and production" of the Southwestern Industrial Area through the continuous efforts of Southwestern engineers, contributing to the efficient development of sour gas
