Description

j j Известны способы создани  подземного хранилища дл  очишенного от сероводорода газа в истощенных газовых или нефт ных месторождени х , содержащих пластовый сероводородный газ. Описываемый способ, согласно изобретению, имеет целью снижение стоимости создани  хранилища. Это достигаетс  тем, что в купольные и прикупольные скважины заканчивают очищенный от сероводорода газ дл  вытеснени  из примыкающей к скважинам зоны пластового газа. Кроме того, с целью увеличени  объема хранилища, через приконтурные скважины вытесн ют на дневную поверхность пластовый газ в промежутки времени между закачками и отборами из хранилища очи-, щенного газа. Проблема хранени  больщих объемов газа вытекает из сун1ествующей сезонности потреблени  газа. При этом наиболее эффективным способом хранени  больщих объемов газа  вл етс  подземное хранение. Однако значительное содержание сероводорода в газовых месторождени х исключает возможность создани  подземного хранилища, очищенного газа в газовой засечке, вследствие предполагаемого смещивани  пластового газа с закаченным и тем самым заражени  сероводородом газа, закаченного в пласт. Создание подземных хранилищ газа, очищенного от сероводорода, в истощенных газовых и нефт ных месторождени х возможно, методом вытеснени  пластового газа, очищенным от сероводорода закаченным газом. Вытеснение неочищенного газа осуществл етс  путем нагнетани  очищенного от сероводорода газа в скважины, расположенные вj j Methods are known for creating an underground storage facility for gas purified from hydrogen sulphide in depleted gas or oil fields containing formation hydrogen sulphide gas. The described method according to the invention aims at reducing the cost of creating a storage facility. This is achieved in that the domed and domed wells terminate the gas purified from hydrogen sulfide to displace from the zone of the gas reservoir adjacent to the wells. In addition, in order to increase the storage volume, through offshore wells, reservoir gas is forced onto the day surface in the intervals between injection and withdrawal from the purified gas storage. The problem of storing large amounts of gas arises from the seasonality of gas consumption. In this case, the most efficient way to store large volumes of gas is underground storage. However, a significant content of hydrogen sulfide in gas fields excludes the possibility of creating an underground storage facility, cleaned gas in a gas notch, due to the anticipated displacement of the gas reservoir with the injected gas and thereby contamination of the gas injected into the formation with hydrogen sulfide. Creating underground gas storages purified from hydrogen sulphide in depleted gas and oil fields is possible using the method of displacing stratal gas purified from hydrogen sulphide by injected gas. The displacement of the crude gas is carried out by injecting the gas, purified from hydrogen sulphide, into the wells located in

To avoid contamination of the injected gas with hydrogen sulfide released from the underlying gas reservoir of the sub-surface water, the wells must be removed from the gas-water contact. Contour wells are used as controls to determine changes in gas composition and pressure and storage. For determining the reservoir pressure on the aquifer of the reservoir and the composition of the displaced gas at its occurrence, contour wells are used. The gas injected into the dome of the reservoir, purified from hydrogen sulfide, is pushed aside by the reservoir gas, due to the slight free diffusion of gases in the porous sphere, a small part is displaced with the reservoir gas. The mixture of two gases creates a gas reservoir in the reservoir, which for a long time protects the bulk of the injected gas from being contaminated with hydrogen sulfide contained in the reservoir gas, as well as for displacing hydrogen sulfide, if necessary, onto the surface.

Предлагаемый способ создани  подземного хранилища ведет к уменьщению затрат средств на удаление неочищенного газа, а поэтому может найти применение при хранении больших объемов газа.The proposed method of creating an underground repository leads to a reduction in the cost of funds for the removal of the raw gas, and therefore can be used when storing large amounts of gas.
