Well JPH-402 in Dongsheng Gas Field set a new drilling cycle record

Recently, the JPH-402 well in Dongsheng Gas Field set a new record for the shortest drilling cycle of the secondary wellbore structure without a guide hole in the Hangzhou Jinqi Engineering Area with a drilling cycle of 28.
39 days, which was 18.
61 days shorter than the design cycle, and the acceleration momentum was strong
.

JPH-402 well is a reservoir development horizontal well deployed by the Research Institute of North China Oil and Gas Branch in the north of the Yishan slope in the Ordos Basin, located in the territory of Hangjin Banner Xini Town, Ordos City, Inner Mongolia, independently designed by the North China Engineering Institute, the second gas production plant is responsible for operation and management, the drilling construction of the West Branch of North China Engineering, the completion drilling depth is 4376 meters, and the completion of the drilling layer Permian system under the lower stone box group box 2 section
.

The JPH-402 well is located in the same well site as the previously completed JPH-426 well, the wellhead distance is only 5 meters, before the drilling, the engineering institute requires all parties to carefully implement the design, the geology, engineering, drilling fluid, cementing and other design technical disclosure, implement the key technical measures, and according to the design requirements to make various preparations
before drilling 。 The second gas production plant responsible for operation and management has always been based on the concept of "safe production, speed up and efficiency", to strengthen production and technical management as the starting point, to accelerate the production and construction progress as the goal, to dig deep into the potential of speed and efficiency, clarify the responsible department, implement the tracking, implementation and supervision of the operation process of the design plan, establish an efficient mechanism of "design review - construction tracking - on-site supervision - complex problem handling - responsibility handling", at the same time, the gas production plant and the engineering institute are closely integrated to guide the construction and solve the "difficult and miscellaneous diseases" on site.
Make every effort to promote the acceleration and efficiency of work
.

The distance between the well and the adjacent well JPH-426 is relatively close, and during the actual drilling process, the relevant carefully collect and sort out the track data of each wellbore of the old well, do a good job in anti-collision monitoring in accordance with the relevant regulations and requirements, and pay close attention to the drilling parameters to ensure anti-slope straightening
.
Through the efforts of all parties, the average mechanical drilling speed of the well reached 10.
63 m/h, which achieved the purpose of speeding up and improving efficiency, and laid a foundation
for accelerating the pace of gas field production.
