翻譯：This chapter deals with the fundamental properties of reservoir rocks. The properties discussed are (1) porosity - a measure of the void space in a rock; (2) Permeability - a measure of the fluid transmissivity of a rock; and (3) fluid saturation - a measure of the gross void space occupied by a fluid. These properties constitute a set of fundamental parameters by which the rock may be described quantitatively.

翻譯：Other additives are often added to the fracturing fluids for special proposes. Corrosion inhibitors may be used if the fracturing fluids might cause corrosion in the tubular goods in the well.Other additives are used to make the part of the fracturing fluid which is moving against the pipe walls behave almost like lubricating oil while the remaining fracturing fluid take an almost solid form to carry the maximum amount of proppant.

翻譯：The HF-HCI mixture (usually 3-percent HF and 12-percent HCI) then is injected. The HF reacts with calys, sand, drilling mud, or cement filtrate to improve permeability near the well-bore.The HCI will not react and is present to keep the PH low, preventing precipitation of HF reaction products. Sent to keep the PH low, preventing precipitation of HF reaction products.

翻譯：After the casing string is run, the next task is cementing the casing in place. An oil well cementing service company is usually called in for this job although, as when casing is run,the rig crew is available to lend assistance.

翻譯：Meanahile ,steel pipes that would carry the oil were being developed . These were the first oil pipelines which take the advantage of the fact the oil is a liqnid. The ideas of a pipeline were not new , water has been transported through pipes for handreds of year ,The oil pipeline were not accepted without a struggle, hower.
