开采面积

It has the prominent ecological functions on preventing sandiness, self-restraint water and adjusting climate. But because of the disturbance of nature and human factors, especially the exploitation of petroleum, the wetland has been developed to be a weak ecosystem gradually.

然而，由于自然环境和人为活动等因素的影响，尤其石油开采已进入莫莫格湿地保护区核心区，都使得莫莫格湿地的面积大量萎缩、盐碱化加重，逐渐向脆弱的生态系统方向发展。

Analysis is made on the influences of the main constructions in the mine on the roof wall rock and the water containing layer, the ubiety between the roof and the interlayer or relative interlayer, the influence of the water containing layer and exploration drilling on jamb mining. The safety mining depth as well as the height of collapsed belt and the cranny guiding water are calculated. Furthermore, the ANSYS software is adopted to simulate the stability of the cover terrane and the maximum permit exposure area.

分析了矿区内主要构造对顶板围岩及含水层影响、顶板与隔水层和相对隔水层位置关系、含水层及勘探钻孔对矿柱回收的影响；计算了冒落带和导水裂隙高度及安全开采深度；用ANSYS有限元软件模拟了空区上覆岩层稳定性及最大允许暴露面积。

If we adopt normal methods to exploit,we can not have any economic benefit,but if we adopt double step horizontal wells,it can increase drainable area greatly,enhance individual well producing rate, achieve the Tarim Oil field's exploiting rule of\"wide spacing,high production\".

若采用常规方式开采，毫无经济效益，而利用双台水平井可大大增加泄油面积，可提高单井产量，实现&稀井高产&的开发效果。
