沙溪庙组

川西致密碎屑岩沙溪庙组气藏是中石化集团主要的天然气生产基地。

Shaximiao formation gas reservoir in the compact clastic rocks of western Sichuan is one of Sino-PEC ′ s main natural gas production bases .

四川盆地西部侏罗系沙溪庙组是河流三角洲滨浅湖沉积为主的红色砂泥岩系，天然气资源相当丰富。

Abundant in natural gas sources , Jurassic Shaximiao Formation in west Sichuan Basin is a red sandstone and shale mainly deposited in fluvial , deltaic shoal faces .

中江地区沙溪庙组地层在钻井过程中一直存在比较严重的垮塌现象，给该区钻井施工带来较大的技术难题和经济上造成较大损失。

Serious collapsing is always existed in the drilling process in Shaximiao formation of Zhongjiang area , which brings technical difficulty in drilling operation and huge economic loss .

新场沙溪庙组气藏是西南油气田的主力气藏之一，目前，该气藏开发已步入中后期产量递减阶段。

As one of the main gas reservoirs in oil and gasfield of southwest Sichuan Basin , Shaximiao reservoir of Xinchang gasfield is now in the production decline stage .

不同成土母质发育的土壤，有机质、全氮、碱解氮、速效磷、速效钾的含量均是在沙溪庙组最高，自流井组次之，遂宁组最低；

Soil from different soil parent materials , organic matter , total nitrogen , alkali-hydrolysable nitrogen , rapidly available phosphorus , rapidly available potassium was the highest in J_ ( 2s ) .

在新场上沙溪庙组气藏的中深定向井施工中，使用高密度的钻井液，存在起下钻摩阻大、测井和下套管困难等问题。

When directional medium-depth wells are drilled , high density drilling fluid is used , the problems take place that frictional resistance is high during trip and running casing and well logging are difficult .
