水平井开发低孔、低渗类单砂体气藏在国内外均取得了较好的成绩，并且近几年在国内多个油田迅速推广。文章主要针对砂泥岩互层型气藏复杂的地质条件及利用水平井开发过程中遇到的困难进行分析，包括单砂体横向展布预测、目标砂体的选择与着陆和钻井轨迹控制问题，提出相应的技术对策。以西部某气田JSN气藏为例，采用对应的技术措施克服困难后，证实了水平井开发在砂泥岩互层型气藏开发中能够取得较好效果。
水平井開髮低孔、低滲類單砂體氣藏在國內外均取得瞭較好的成績，併且近幾年在國內多箇油田迅速推廣。文章主要針對砂泥巖互層型氣藏複雜的地質條件及利用水平井開髮過程中遇到的睏難進行分析，包括單砂體橫嚮展佈預測、目標砂體的選擇與著陸和鑽井軌跡控製問題，提齣相應的技術對策。以西部某氣田JSN氣藏為例，採用對應的技術措施剋服睏難後，證實瞭水平井開髮在砂泥巖互層型氣藏開髮中能夠取得較好效果。

The horizontal wells development has made good achievement at home and abroad in low porosity and low permeability gas-pool with definite single formation,then,it is rapidly promoted in many domestic oilfield in recent years,In the article the complicated geological conditions in the Gas Pool of sand shale and thin interbed and some problems of Horizontal Wells Development are discussed,such as distribution of sand bodies.selection of target formation and direction control,then some corresponding countermeasures are come up with.JSN gas reservoir in a western gas field as an example,once corresponding technical measures be taken to overcome the problems,it is confirmed that favourable effects must be obtained in horizontal wells development in the Gas Pool of sand shale and thin interbed.
