隔气层

D gas field is a structural-lithological reservoir. The main gas formation is marine shoreface sandstone dam and shoreface beach sand. The reservoir has serious anisotropy. This mainly shows the coombe on the surface and the thin interlayer in reservoir.

D气田为构造－岩性油气藏，主力气层为海相临滨砂坝和临滨滩砂，储集层非均质性严重，主要表现为平面上的冲沟和储层内部厚度较薄的隔夹层。

In combination with the geological features of the ga wells in West Sichuan, such as multi-payzone high pressure gradients and a large lithological change in channel sand bodies, etc., the casing cementing and perforation completion were adopted for the main well and branch holes in the well group and the interzonal pressure seals of the main well and branch holes, and the separate well fracturing and producing were all realized through a completion string with dual-tubing and dual-packer.

结合川西地区气井多产层、高压力梯度、河道砂体岩性变化大等地质特点，该井组主井眼和分支井眼均采用套管固井、射孔完成，通过双油管和双封隔器的完井管柱实现了主井眼和分支井眼的层间压力分隔和分井压裂、分井采气。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
