9、as In a seismic survey, the geophysical (地球物理的）contractors crew lays out a line or several lines of sensitive receivers（检波器）, called geophones or jugs（地震检波器）, on the ground. Then explosions（爆炸） or mechanical vibrations（机械振动） are created on the surface. The geophones record the energy reflected back

14、-Recovering ResourcesAfter drilling has located a reservoir of oil or natural gas, the operating companys production department takes over the task of bringing the resource to the surface. Petroleum is not produced from underground lakes. Rather, oil and gas are contained in the pores and fractures

15、of certain sedimentary rocks(沉积岩） in the same way that water is held in a sponge. In mature producing areas, recovering more oil and gas from old wells is an important job. Producing oil and natural gas (1)Production-Recovering Resources(2) Oil Recovery MethodsPrimary recovery(一次采油）一次采油）Infill drill

16、ing（加密钻井）：drilling more wells into the same pool so the oil does not have to travel as far through the rock to reach a wellbore. Directional wells are often used for infill drilling. Secondary recovery（二次采油）（二次采油）Further oil production can be obtained by injecting water or natural gas to maintain re

When dissolved, these liquids reduce surface tension 表面张力
